From 5210989283c28b909e13efb61c0e298c178bb76f Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 1 Aug 2019 14:36:36 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: call vtu_getnext directly in vlan_del Wrapping mv88e6xxx_vtu_getnext makes the code less easy to read. Explicit the call to mv88e6xxx_vtu_getnext in _mv88e6xxx_port_vlan_del and the return value expected by switchdev in case of software VLANs. At the same time, rename the helper using an old underscore convention. Signed-off-by: Vivien Didelot Signed-off-by: David S.
